Q: How do I fix Mac OSX screen from going to vertical lines when on internet?

When going to the Internet  my Mac will instead fill the screen with a field of tightly spaced vertical lines. It requires rebooting to get out of it. Anyone have insight on this?

I did run AVG cleaning last night

    Please post a screenshot of the anomaly.


    Due to a bug associated with this support site, image attachments may or may not appear. Try it anyway.

     


     

    Screenshots (Mac):

     

    To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot named "Screen Shot...." followed by a date and time on your Desktop.

     

     

    When you post your response, click the "camera" icon above the text field:

    This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button. If you are not using full screen mode you can simply drag the image into the text entry field.

     

    ⌘ Shift 4 and then pressing the space bar captures the frontmost window.

     

    ⌘ Shift 3 captures the entire screen.

     

    Don't capture or upload any information you consider personal. To edit an existing screenshot, read How to edit a screenshot.

     

    Drag the screenshot to the Trash after you post your reply.
